I'm with you. There is a security interest in having as complete as possible a database of DNA, but there is a contrary interest in privacy that I believe trumps the security interest. One reason for this is that, alas, your friends are simply wrong to think that simply because one is innocent one has nothing to fear from the government. Innocent people are convicted perhaps more often than your friends think. I recommend a book called Actual Innocence , which along with the Innocence Project explores how false convictions occur. One way they seem to occur is through the misuse of biological evidence. Or Google "Fred Zain" and "Ralph Erdmann" to learn more about the laboratory misconduct. The case of the Guilford Four in Britain is instructive, too. Sadly, the most prudent course and the course that best protects innocent people is not to allow the state access to the DNA of people charged but found to be innocent. This will, of course, in some cases diminish people's security; but the...

Both. General capacities and inclinations for thought, feeling, and conduct are biologically based (not just in our genes but in virtually all our tissues). But the specific way those capacities and inclinations are conceptualized and formulated in principle, narrative, argument, and prohibition shapes, limits, and cultivates them--often in different ways by different people and societies.

About universal morality: while it's true that among cultures (as among individuals within any culture) there are variation in moral beliefs (as well as scientific beliefs), there are general (nearly universal, so far as I can tell) moral categories. One finds incest regulations, for example, in every society (though the boundaries of those prohibitions vary). Rules concerning possession, killing, and even, arguably, the sacred are more or less universal. I would be pretty reluctant to walk into any human society and start taking bites out of people's children. Moral beliefs and conduct do exhibit variation, but variation by itself doesn't disprove the existence of universal commonalities. Any pharmacist will tell you that different people respond to different drugs differently, but that doesn't refute the universal laws of chemistry. Human moral life, then, exhibits both remarkable variation and remarkable commonality. As you say, there are various possible explanations for this. ...

Ah, but how can proper English be defined? Like life, there is, I'm afraid, no absolutely precise definition. The boundary is likely to move when considering different contexts (e.g. medical, legal, taxonomic, robotic, spiritual); and even in many of these contexts the boundary is likely to remain vague, or at least provisional. One is likely to feel that there simply must be a clean and formulable line between what's alive and not alive. But my sense of things is that this just isn't the case. In any event, from where I sit, you're both alive and good writer in English.

Whether and how to have a child is one of the most intimate and personal matters of life, whatever one's religion. So, ultimately you must make the decision as to what is most fitting for you. I cannot write as a Muslim or as one expert in Muslim theology. As a philosopher, however, I can say that I find nothing objectionable per se in the practice of using ova from a third party in order to generate a baby to which your wife can give birth, that can carry your genetic codes, and that the two of you can raise. I would offer this cautionary note, however. Sometimes the costs of such procedures can be terribly high. That being the case, one ought to consider whether in an (a) already over populated world, where (b) many children stand in need of adoption, and (c ) where many other problems demand attention it is proper to expend so many resources to bring a single child into existence. Conceiving, birthing, and raising a child using a third-party donor may be the best option for you. But do consider...
